Geforce GTX 690 vs Geforce GTX 770

Intro

The Geforce GTX 690 has a core clock frequency of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Compare all that to the Geforce GTX 770, which has GPU clock speed of 1046 MHz, and 2048 MB of GDDR5 RAM running at 1753 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 690 is superior to the Geforce GTX 770, and very much so. (explain)

Geforce GTX 690 58560 Mpixels/sec
Geforce GTX 770 33472 Mpixels/sec
Difference: 25088 (75%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
